Summary0015919: Building CUDA files fails when source path contains parenthesis
DescriptionWhen working in a source path containing "()" I get the following error upon building CUDA files:

15:13 sandbox$ make
[ 6%] Building NVCC (Device) object CMakeFiles/githash.dir//./githash_generated_float3.cu.o
/bin/sh: 1: Syntax error: "(" unexpected
CMakeFiles/githash.dir/build.make:167: recipe for target 'CMakeFiles/githash.dir/./githash_generated_float3.cu.o' failed
make[2]: *** [CMakeFiles/githash.dir/./githash_generated_float3.cu.o] Error 2

make[1]: *** [CMakeFiles/githash.dir/all] Error 2
Makefile:76: recipe for target 'all' failed
make: *** [all] Error 2


The following fix provided by ngladitz in #cmake solves the issue on my machine:

Sorry, I forgot to give credit to http://bikulov.org/blog/2013/12/24/example-of-cmake-file-for-cuda-plus-cpp-code/ [^] for the CMakeLists.txt!

Thanks. Please try this fix:

 FindCUDA: Support special characters in path

Does work for me.

Actually the first VERBATIM is enough to get it running. However my file is not identically to the one in the fix, the line numbers differ and some neighbouring ones as well.

The change in 0015919:0040246 introduced a regression discussed here:

 FindCUDA.cmake regression in 3.5.0-rc2
 http://thread.gmane.org/gmane.comp.programming.tools.cmake.devel/15827 [^]

The fix for now is to revert use of VERBATIM with Visual Studio generators, but that will not affect the use case posted here.
